| | * iio: adc: at91_adc: allow to use full range of startup timeJan Leupold2015-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DT-Property "atmel,adc-startup-time" is stored in an u8 for a microsecond value. When trying to increase the value of STARTUP in Register AT91_ADC_MR some higher values can't be reached. Change the type in function parameter and private structure field from u8 to u32.

| | * iio: DAC: ad5624r_spi: fix bit shift of output data valueJM Friedt2015-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value sent on the SPI bus is shifted by an erroneous number of bits. The shift value was already computed in the iio_chan_spec structure and hence subtracting this argument to 16 yields an erroneous data position in the SPI stream.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 1c6c69525b40 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. So pass the IRQF_ONESHOT flag in this case. The semantic patch that makes this change is available in scripts/coccinelle/misc/irqf_oneshot.cocci.

| | * hid-sensor: Fix suspend/resume delaySrinivas Pandruvada2015-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default all the sensors are runtime suspended state (lowest power state). During Linux suspend process, all the run time suspended devices are resumed and then suspended. This caused all sensors to power up and introduced delay in suspend time, when we introduced runtime PM for HID sensors. The opposite process happens during resume process. To fix this, we do powerup process of the sensors only when the request is issued from user (raw or tiggerred). In this way when runtime, resume calls for powerup it will simply return as this will not match user requested state. Note this is a regression fix as the increase in suspend / resume times can be substantial (report of 8 seconds on Len's laptop!)

Given Linus announced a 4.8rc coming up, hopefully time for one more lot of IIO patches this cycle. Some of these are actually improvements / fixes for patches earlier in the cycle. New device support * st_accel driver - support devices with 8 bit channels. Cleanup * A general cleanup of the iio tools under /tools/ from Hartmut. I'm more than a little embarassed by how bad some of these were! Are well, much more refined and less bug prone now. These cover lots of stuff like unhandled error returns, memory leaks as well as general refactoring to tidy the code up. * iio_simple_dummy - fix memory leaks in the init functions, drop some pointless error returns from functions that never generate errors and make the module parameter explicitly unsigned. * More buffer handling reworks from Lars-Peter, this time targetting hardware buffers (a little used corner that looks likely to get more use in the near future). Specifically: - Always compute the masklength as inkernel buffer users may need it. - Add a means of labeling which buffer modes a given buffer implementation supports. - In the case of hardware buffers, require strict scan matching rather than matching to a superset. Currently the demux is bypassed by these drivers (this may well not change for efficiency reasons) so allowing a superset of channels to be selected would otherwise lead to more data than requested confusing userspace. Driver funcationality improvments * mmc35240 - adds a compensation to the raw values as borrowed form Memsic's own input driver. * mma8452 - event support - event debouncing - high pass filter configuration - triggers * vf610 - allow conversion mode to be adjusted Fixlets * mmc35240 - Off by one error that by coincidence had no real effect. - i2c_device_name should be lowercase. - Lack of null terminator at end of attributes array. - Avoid computing the fractional part of the magnetic field by moving the scaling into userspace where floating point is available to simplify the maths. - Use a smaller sleep before assuming the measurement is done. This is safe and improves the possible polling rate. - Fix sensitivity on z-axis - datasheet disagrees with Memsic's releasedd code and the value used in the code seems to be correct. * stk3310 - make a local variable signed to ensure error handling works. * twl4030 - fix calculation of the temperature sense current - bug unlikely to have ever been noticed as the difference is small. - Fix errors in descriptions.

So far, the mode used was low-power, which is enabled by default now. Beside that, the modes normal and high-speed are selectable as well. Use the new device tree property which specifies the maximum ADC conversion clock frequencies. Depending on the mode used, the available resulting conversion frequency are calculated dynamically.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bit mask to read the setting of the constant current source for measuring the NTC voltage was the wrong one. Since default value is initialized to the lowest level (000 = 10uA) the difference was probably never noticed in practice. Signed-off-by: H.
